Working Principles

The TCAN1051DQ1 is designed to enable reliable communication between microcontrollers in automotive applications using the Controller Area Network (CAN) protocol. It operates by converting digital signals from the microcontroller into differential voltage signals suitable for transmission over the CAN bus. The transceiver also receives differential voltage signals from the bus and converts them back into digital signals for the microcontroller to process.

Detailed Application Field Plans

The TCAN1051DQ1 is primarily used in automotive systems that require robust and high-speed communication, such as:

1. Engine control units
2. Transmission control modules
3. Body control modules
4. Advanced driver-assistance systems (ADAS)
5. Infotainment systems
